''Eileanchelys'' is an extinct genus of primitive turtle from the Middle Jurassic (Bathonian) period some 164 million years ago of Britain. Only one species is recorded, ''Eileanchelys waldmani''. It is the best-represented turtle from the Middle Jurassic, because of the amount of specimens that can be assigned to it. The turtle is also one of the oldest turtles ever found to be aquatic, and might represent a milestone in turtle evolution. ==Discovery and naming== In 2009, two specimens from the National Museums of Scotland, Edinburgh, including NMS G 2004.31.15 and NMS G 2004.31.16a–f, were found to differ from other turtles from the area and age. It was decided that they represented a new genus and species, and were named ''Eileanchelys waldmani'' by Jérémy Anquetin and his colleagues. The specimen NMS G 2004.31.15 was designated as the holotype, and NMS G 2004.31.16a-f, the paratypes. NMS G 2004.31.16 includes at least five, and possibly six, different individuals, all in one block. The holotype of ''Eileanchelys'' is a partial skull. Both blocks were found in Cladach a'Ghlinne, Scotland.〔
